Diagnostic challenges in synchronous ovarian metastasis from rectal cancer: A case report.
Article in Medicine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionOvarian metastases from rectal cancer are infrequent; thus it might be hard to diagnose and treat them. Our study introduces a challenging case which highlights our method in addressing such an issue. PATIENTS CONCERNS: A 74-year-old woman was admitted to our Unit showing abdominal pain, vomit, and a gross abdominal mass located in the right iliac fossa and mesogastrium. Oncological markers recorded following abnormalities: carbohydrate antigen 19.9 (Ca19.9) = 453.40 U/mL, carbohydrate antigen 125 (Ca125) = 88.3 U/mL. DIAGNOSIS: Such a metastatic tumor being difficult to diagnose, we could not achieve a precise preoperative diagnosis. We entered the operating room with a histologic diagnosis that was highly suspicious of colon adenocarcinoma. During surgery, frozen section analysis was positive for primary ovarian cancer. Thanks to the immunohistochemistry test on the histologic specimen, which might be very helpful in diagnosing such metastatic tumor, final pathology report documented ovarian metastasis from rectal cancer.
interventionsWe performed total hysterectomy with bilateral salpingo-oophorectomy and low anterior resection of the rectum with a terminal colostomy. Adjuvant chemotherapy was administered for 6 months using FOLFOX plus panitumumab in first-line therapy. OUTCOME: At 8 months from surgery, during follow-up, a local pelvic progression of disease was detected, leading to second-line chemotherapy treatment.
conclusionCorrect differential diagnosis between primary and metastatic ovarian tumors is paramount in choosing the best treatment which leads to the best possible outcome. In ovarian metastatic tumors, immunohistochemistry could represent an optimal diagnostic tool.
